I have not looked at all of the diy thread for a long time and I cannot recall clearly but I think there is a link to a clear drawing of how the antenna works, it is a kind of bifilar winding, the wire is folded in half and wound about a central point starting with the mid point of the wire so to make a large one you will require a very long length of very fine wire that you have to manage as you wind your flat pancake coil. Sorry but I don't have any photos of mine and I don't want to take them apart to take pictures. The first antenna I wound was on a piece of thin stiff cardboard a rectangle to fit into the case and I covered one side with double sided tape so the winding would stay in place when done I coated it with a few shots of spray paint to encapsulate the winding and insure it stayed in place. Good luck and best regards Moray James.
